true story: when i lived in NYC, i used to go to the Apple store to charge my iPhone when it was low on battery while I was out all day and needed my phone to communicate w/ people, make plans, etc. Especially cool bc the one on Fifth Ave. is 24 hours! I went there once around midnight and just plopped my phone down on one of the cradles for 15 min while i pretended to be interested in looking at their iPhone :) works like a charm!
